How to convert JPG or PNG images to PDF
- Select one or more JPG or PNG images, or drag them into the upload area.
- Arrange the images in the order you want them to appear in the PDF.
- Choose A4, US Letter or image-sized pages. Adjust orientation, margins and how each image fits.
- Optionally enable PDF size optimization, then create and download your document.
Combine multiple images into one PDF
Each selected image becomes a separate PDF page. This is useful for joining photographs of a form, handwritten notes, receipts, or scans into a single document. You can reorder or remove images before conversion. The tool accepts up to 30 images per document, with a maximum of 25 MB per image and 120 MB total input. Browser memory may impose additional limits.
Choose A4, US Letter or original image dimensions
A4 measures 210 × 297 mm and is commonly used internationally. US Letter measures 8.5 × 11 inches and is common in the United States and Canada. Choose portrait or landscape for either paper size. Image-sized pages use the image's pixel dimensions with a 96-pixels-per-inch conversion; this is a convenient layout, not a guarantee of physical print dimensions or original DPI metadata.
Fit whole image preserves all visible content and may leave blank space. Fill page crops the image at its centre to fill the printable area, which can cut off text or edges. For documents, fit whole image is usually safer.
How PDF size optimization works
Enable optimization to re-encode images as JPEG at your selected quality and maximum dimensions. This can substantially reduce the size of photographic PDFs, but fine text, line art and transparent graphics may lose detail. JPEG does not preserve transparency; transparent areas become white. Turning optimization off avoids the lower JPEG quality setting, but image dimensions are still limited by the selected maximum dimension for browser performance.
This tool does not guarantee a PDF below a specific KB or MB limit. PDF overhead, image complexity, resolution and page count all affect the final file size. If an upload portal has a strict maximum, check the downloaded PDF's actual size before submitting it.
Privacy and supported files
PDF creation happens in your browser. Source images are not uploaded to ImgPocket for conversion. JPG and PNG are supported; HEIC, SVG, animated images and existing PDF files are not supported by this converter. Keep original images if you need to preserve their metadata or edit them later.
Frequently asked questions
Can I combine several JPG files into one PDF?
Yes. Add up to 30 JPG or PNG images and arrange their order before converting. Each image becomes one PDF page.
Will my images be uploaded?
No. Images are processed locally in your browser. The PDF is generated on your device.
Can I convert a PNG with transparency?
Yes, but the tool uses a white background when preparing image pages. If JPEG optimization is enabled, transparency cannot be retained.
Can I make a PDF under 100 KB or 1 MB?
You can reduce image quality and maximum dimensions, but exact PDF file sizes are not guaranteed. Check the downloaded PDF before using it.
Can I choose a paper size?
Yes. Choose A4, US Letter or a page sized to each image, plus orientation, margins and fit options.
